How does driving too slowly affect other drivers?

Answer: C — May cause impatience and unsafe overtaking

Driving too slowly can lead to impatience among other drivers, which may result in unsafe overtaking maneuvers. When a vehicle is moving significantly slower than the flowing traffic speed, it disrupts the natural rhythm of the road and can frustrate drivers behind. This frustration may lead to drivers attempting risky passes in order to get around the slower vehicle, increasing the likelihood of accidents. Thus, maintaining a speed that's consistent with other traffic is essential for safe driving and overall road safety.
